Thanks Wayne.
The finished pilot's seat is shown below. Sorry for the poor focus on the second pic - cell phone. The seat base and the armour plate are steel photoetched parts supplied with the kit. These are a lot thicker than the Eduard PE most of use are used to.
Below can be seen the seat in place in the cockpit.
Back onto the wings and that awkward seam in the concave section near the trailing edge, I pulled out my handy-dandy home-made sanding stick. Some time ago I made this tool out of sprue for sanding in tight spaces. The plastic was held over a flame until just soft and then was bent and squashed against my workbench. The other side was done similarly but with a smaller head. These ends are filed to the desired shape and then get a pieces of sand paper CA glued to them.
Here you can see the start of the work with the tool. The small end was curved with a file to match the curvature of the wing and sandpaper is stuck to the shaped end. It doesn't take long for the sandpaper to wear down so the option is to either glue another piece on or, what I usually do, cut a small pice of paper and just push it with the stick.
The work is time consuming but gets results - eventually. I'll be at this for a few days to get it right and I have already broken off the aileron actuator rod in the process.
Below are two not-so-great pics of some of the stuff I've thrown into the back seat. It's a tight space so it's hard to get the camera angle right but there's a jerry can a sack-o-stuff and a leather satchel which I originally thought was a life vest. All of this stuff, and more, comes on a dedicated sprue of paraphernalia that includes folded blankets, oil drums, satchels and a bucket to go with several standing and sitting figures.
Finally, here's the firewall with its nice detail, all of which will disappear once the cowls go on.
Thanks again for your continued interest.
